Hi Richard,
Ah. TypeError. *grin* At least, a conceptual one.
The code above accumulates the fileList with the following:
fileList.append( files )
But the problem is that your fileList is a list of lists of file names.
What you really want to do is:
fileList.extend( files )
to hold a flat list of file names in fileList. The extend() method of a
list allows the list to absorb the elements of the other input list.
Concretely, your fileList probably looks something like this:
[['hello.txt'], ['notes.txt', 'blah.txt']]
where you really want to have something like this instead:
['hello.txt', 'notes.txt', 'blah.txt']
Hope this helps!
